Alabama Retirement Income Tax: What Huntsville Retirees Actually Pay
Alabama is one of the most generous states in the country for retirement income — but only if you understand the one distinction that decides everything: defined-benefit vs. defined-contribution.
What's taxed and what isn't
| Income source | Alabama state tax |
|---|---|
| Social Security benefits | Exempt — 100%, regardless of income |
| Military retirement pay | Exempt |
| Railroad Retirement (Tier 1 & Tier 2) | Exempt |
| TVA pension benefits | Exempt |
| Defined-benefit pension (state, federal, or private) | Exempt |
| Traditional IRA / 401(k) withdrawals | Taxable at 2%–5% (with 65+ exclusion below) |
| Interest, dividends, capital gains | Taxable as ordinary income (2%–5%) |
The distinction nobody explains: defined-benefit vs. defined-contribution
Most guides say "Alabama exempts government pensions." That's not the rule. The actual dividing line in Alabama law is defined benefit vs. defined contribution, not public vs. private. If your former employer pays you a fixed monthly pension for life — whether that employer is a state agency or a Fortune 500 company — that income is fully exempt. If instead you're drawing down a pot of money you accumulated in a 401(k) or IRA, those withdrawals are taxable.
This matters because a retiree with a traditional corporate pension can owe essentially zero Alabama income tax, while a neighbor with the same total income coming out of a 401(k) pays the 2%–5% rate on most of it. Same dollars, very different bill.
The 65+ retirement exclusion just doubled
For taxable retirement distributions (your IRA/401(k) money), Alabama lets residents 65 and older exclude a flat amount off the top:
| Tax year | Amount excluded (age 65+) |
|---|---|
| 2025 | First $6,000 of taxable retirement income |
| 2026 and after | First $12,000 of taxable retirement income |
This increase was enacted into law (HB388) and takes effect for tax year 2026. For a couple both over 65, the exclusion applies per qualifying taxpayer.
The quiet bonus: Alabama lets you deduct your federal income tax
Alabama is one of a small number of states that lets you deduct the federal income tax you paid from your state taxable income. For a retiree drawing meaningful taxable income, that deduction shrinks the Alabama base further — an effect most state comparisons leave out entirely.
The rates themselves are low
Alabama's income tax tops out at 5%, and that top rate kicks in quickly, so for planning purposes most retirees can treat their taxable retirement income as taxed at roughly 5% — before the 65+ exclusion and federal-tax deduction bring it down. You only need to file an Alabama return if gross income exceeds the filing threshold ($4,000 single / $10,500 married filing jointly).
Where this leaves a typical Huntsville retiree
A retired couple living on Social Security plus a corporate pension can realistically owe $0 in Alabama income tax. A couple living primarily on 401(k) withdrawals will owe something — but after the 2026 exclusion and the federal-tax deduction, it's modest. Pair that with the nation's lowest property tax (see the over-65 property tax guide) and you can see why the income side, not the housing inventory, is what pulls retirees to North Alabama.

Verified for tax year 2025 (returns filed 2026) against the Alabama Department of Revenue ("Income Exempt from Alabama Income Taxation"), Code of Alabama §40-18-19, and Act/HB388 raising the 65+ exclusion to $12,000 effective Jan 1, 2026.
